I was doing mdma and 3cmc a lot past year (3cmc more often). I tried to do mdma a few Times this year but it didnt worked for me, I know it was good stuff cuz my friend did those too and it was fine to them. I did 3cmc 2 months ago and it worked. I did mdma in crystal like a month ago (0.5g) I felt tired and didnt want to do anything besides laying On bed, my pupils where bigger and I was sweating a lot ( like i would do normally on mdma. I always could do a lot of stims, mdma too like 1g per night or 10g of 3cmc if I was having money (was abusing 3cmc that time).My serotonin receptors should be good cuz I did lsd and it worked well. So my question is, will I ever be good? What should I do to reduce my tollerance?

Ps. English isnt my native language so sorry if I got some spelling mistakes.
